Xerox Commercial Services is eliminating about 139 jobs at its call center in Cary in response to the reduced needs of one of its clients.

The company initially notified the state that it planned to lay off 168 workers in Cary, but company spokesman Bill McKee said that number was subsequently revised downward. He also noted that some of the laid-off workers — the company isn’t saying how many — will be rehired to work for other clients.

“That’s the very nature of this whole call center customer care cyclical business,” McKee said. “While we are winding down operations for one of our customers, we are at the same time hiring for other of our customers.”

“This is a very difficult decision,” he added. “We expect to be able to place a number of these (workers) in other jobs, comparable jobs, in Cary.”

McKee also confirmed that local executives requested that Cary police be on hand Friday morning when employees received layoff notices.

“They were being cautious,” McKee said. “There were no incidents at all.”

Xerox has 1,800 workers in Cary and more than 3,500 throughout the Triangle, a number that has been growing overall despite periodic layoffs. Xerox entered the call center business in 2010 when it acquired Affiliated Computer Services.
